Way too little information to really psychoanalyze this guy (not that we are trained in that anyway), but MerryH is exactly right. He wasn't interested in dating you. There is not much more to think about than just that. I don't know why you think that he is the perfect one for you, but you really need to rethink that. He can't be the perfect one for you if he is not interested in you as you are in him. Don't spend another moment wondering about this guy, his sexual orientation, his love life, or anything like that.
Good luck.
